General description The machine, as herein disclosed, is provided withfour banks of amount keys and one divided bank having six clerks keysand three transaction keys. These banks of keys control the adjustn'ientof the indicators and 0f the type carriers. A ledger number device isalso provided for printing account numbers or any other identifyingcharacters. A detail strip is provided upon which a record of eachtransaction tail strip and record remains in the machine. The printer isalso adapted to print on either a check or slip. The machine is normallyadapted to print a stub check, however, if a transaction key isdepressed, the check issuing mechanism will be automatically thrown off,because during an operation on which a-transaction key is depressed, itis desired always to print on a slip An on and off knob is provided formanually controlling the issuing. of checks. However, even when the knobis in the off position, and the machine is operated with a transactionkey depressed, the printing mechanism will be automatically controlledto make one print on an inserted slip. A reversible ribbon is provided,which is carried on a removable frame, to permit easier changing ofribbons. The ledger number device is also carried on this removableframe.

Key banks The machine is provided with four banks of amount keys (Figs.1 and 3) slidably mounted in frames 31 and held in their outer positionsby springs 32. WVhen the keys are depressed, they are adapted to controlthe differential positioning of a gear segment Pivoted on the segment33'by means of two links is a latch 41, adapted to be held in engagementwith a driving segment 42 by a spring 43. The spring 43 is disposedbetween a lug on the gear segment 33 and a latch arm 44, pivoted on thesegment 33. The latch arm 44 has an upwardly extending bifurcated armadapted to engage a stud on the latch 41, thereby tending to hold thelatch against the driving segment A2. The driving segment 42 is securedto a shaft 75. The shaft 75 is oscillated once during, each operation ofthe machine by a main operating shaft 76 (Fig. 3), through an arm 77secured thereto and a link 78 which connects the arm 77 with an arm 79secured to the shaft 75. The arm 79 is longer than the arm 77. Anysuitable device, such as the operating handle 80 (Fig. 1) may beemployed forgiving the shaft 76 one complete is printed, which de-'rotation at each operation of the machine, which rotation will cause theshaft 75 to be rocked first clockwise and then counter-clockwise, asviewed in Fig. 3, due to the ditl'er ence in lengths of the arms 77 and79. The arm 77 is located on the shaft 76 in such a manner as to rockthe shaft 75, first clockwise, then counter-clockwise past its homeposition, and then clockwic back to its home position when the shaft 76is rotated in the direction of the arrow. The movement past the homeposition is for the purpose of releasing the depressed keys at the endof an operation as shown and described in the above mentioned patent.

During the first clockwise movement of the driving segment 42 the footof the latch 41 will be moved into engagement with a shoulder by thespring 4.3, when the shoulder 82 registers with the latch. During thecounter-clockwise movement of the driving segment 42, the latch arm 44comes into contact with the end of the depressed key and causes thelatch to be disengaged from the driver -12. thereby stopping the gearsegment 33 in a position commensurate with the dept-es 1 key. In thismanner the gear scgmen 33 positioned differentially under control of thedepressed key 30.

The segn'icnt 33 meshes with a gear 3%. (see also Figs. 4- and 5). Thegears 34; (one for each bank of keys) are carried on the ends of nestedsleeves 35 carried on a rod 36 supported by the side frames of themachine. li ach of the gears Simeshes with a gear 37 on a shaft 92rigidly connected by mcans of a sleeve (not shown), to an indicator 39adapted to be adjusted according to the differential adjustment of thegear segme t- 33. The clerks indicators are positioned in identicallythe same manner as the amount indicaters, and therefore, no furtherdescription will be given thereof. 7

The segment 33 is also adapted to cause amounts to he entered. into atotalizer by the gear 34. and a pinion (Fig. 3) mes ing therewith.Secured to the side of the pinion is a pinion 4.6, loosely mounted on ashaft 47 carried by the frames 31. Also mounted. on the shaft 47 is agear 48 which lies besid the gear 46. Secured to the gear 43 is a totalizer wheel l9 provided with suitable characters for reading theamount on the totalizer. Mounted. on a rockahle shaft 50 is a pluralityof arms 51 each carrying a wide pinion 52 adapted to be rocked intoengagement with the gears 46 and 48, for coupling them together when thesegment 33 is being differentially positioned. In this manner theamounts as determined by the differential novement of the segment undercontrol of the depressed key are accumulated into the totalizer 49. Theabove mechanism old and well known in the art, and is shown in theabove-mentioned Cl-eal and Reinhard transaction key lower endof' thelink rack f94 upwardly,

I ,Transactionindicator A special indicator64 (Figs. 1 and 6) isprovided for indicating cash, received-onaccount, charge, and paid-outtransactions. This indicator is undercontrol ofthe Each key'65 is provided with a pin 66 which projects into the planeofa lever 67 pivoted ona stud 68 carried bv the left-hand frame 31 ofthe machine. W Pivoted tothe lever 67 is a link 69 slotted at its low-er end to surround astud70, I carried by an arm 71, pivoted on a stud 1n the frame 31. Aspring 7 2 normally holds a roller 73 carried by the arm 71 inengagement with a cam 74 pinned to the rock shaft- 75. When theicam 7.4is'rockedin the direction-of the arrow (Fig.6), it-will cause the' arm71 to be moved downwardly and, by means of a spring 81 stretched betweenthe stud and a stud on the link 69 will cause the link 69 tobe moveddownwardly to rock the lever67 in a'counter clockwise direction. Thismovement of the lever 67 will cause one of-a plurality of projectionsthereon to come into contact with the stud 66 of the particular key 65depressed, whereupon the lever 67 and link 69 will be stopped, but thelever: 71 will be permitted to continue to move, thereby stretching thespring 81 and lowering the stud 70 in; a slot formed inthe 69. Thiswillcause the lever 67 to 'be positionedunder control of the depressed key165, therebydiiferentially positioning a stud 91'thereon-for the purposeof controlling the adjustment'of the indicator -64 I The indicator 64 issecured to the sliaft 9 2 carried by the two left frames 31. I To theshaft 92 -is' also secured'a pinion 93 meshing witharack 94 slidablymounted on two studs 95. r A spring96 normally tends to move the doingsoby an alining 'lever 97 pivoted on a stud 98 carriedby theleft frame 31;The

This movement of the lever but is prevented from lowerend of the lever97is provided with a stud 99 cooperating with a cam surface 98 on a mm100, secured to the cam shaft 76.

i ,When theshaft 76 begins to rotate in the di- (Fig. 6), the lever 97rection of the arrow will be rocked in a-clockwise direction, therebydisengaging a'nose in the rack 94 which permits the spring 96 to carrythe rack upwardly until it is stopped by the stud 91.- The stud 91carried byithe lever 67 projects through a slot in a link 105 pivoted onan arm 106 having secured thereto a stud 107 which projects into a slotin the rack 94. 7 After the rack 94 has been released a as justmentloned the lever 67 willbe moved bythe camarm 74 to'position it undercontrol.

of the depressed key 65v as above described. 67'will cause the rack 94to be moved downwardly, thereby adjusting the indicator according to thedif ferential movement of the lever 67 Near the end of the operation andbefore the lever 67 is again permitted to move to its home po-.

sition, the aliner-arm 97 is again rocked counter-clockwise to cause thenose thereon'to be engaged with one of the notches in the rack 94,thereby maintaining the indicator 64 e in itsadju'sted position. Aspring 108 nor-, mally tends to rock the arm 97 to engage it with therack 94.

The lever 67 is provided with teeth which mesh with a segment notches112. An aliner 113 is adapted to be engaged therewith by a block 114secured to the cam 100 after the lever 67 has been adjusted therebyholding the lever 67 in its adjustedposition after the cam 74 becomesdisengaged from the roller 73. Near the end of the operation of themachine the aliner 113 is permitted to rock out of engagement with thesegment 111 thereby permitting the spring 72 to return the arm 71 andlever 67 to their home positions.

111 provided with Transaction type carrier Atspecial type carrier 110(Fig. 4) has been provided for printing the kind of transaction beingentered. This type carrier is secured to the left end of the innermostsleeve 59 (Figs. 4 and 5) and is adapted to be adjusted by the lever 67(Fig. 6). As before mentioned the lever 67 is provided with teeth whichmesh with the segment 111 connected with a. segment 57 by one of thesleeves 35, and meshes with a segment 58 secured to the innermost sleeve59, to which is also secured the type carrier'llO. Fromithis it canbeseen that the type carrier 110 will be adjusted according, to thedifferential adjustment of the lever .67 as controlled by the depressed.

' Ledger number device 7 for recording ledger numbers, or any otherthereon from a notch data which might be desired, on the check which isissued, or upon the slip. This device consists of six type carriers(Figs. 2, 4, and 11) adjusted by levers 116. The type carriers 115 aresecured to the ends of nested sleeves 117 (Fig. 11) which have securedto the other ends thereof segments 118 with which segments 119 mesh. Thesegments 119 are secured to the ends of nested sleeves 120 to the otherend of which are secured arms 121. The levers 116 are adjustably securedto arms 121 by screws 122, thereby perl'nitting accurate adjusting ofthe levers 116 with the characters engaged on the index plates shown inFig. 1. The levers 116 are held in their adjusted positions byspring-pressed pawls 123 pivoted thereto and which engage notches 12 iout in arcuate bars 125 carried by a frame 126, which is adapted to beremoved from the machine. A bar 1.25 is provided for each lever 116, allbars being secured to the above-mentioned frame by studs 127 (see Fig.2). The inner ends of the studs 127 support a bracket 128 which isprovided for supporting a stud 129 upon which the sleeves 120 aremounted. The method of removing this frame from the ma chine will bedescribed in dtail when considering the ribbon mechanism.

Spring actuated aliners 130 (Fig. 11), are provided for holding the typewheels in alinement and cooperate with notches cut in the segments 118.T hose aliners are carried upon a stud mounted on the frame 126.

0710070 assu ing mechanism The method of printing the data shown on thecheck (Figs. 13 and 1 1), other than the ledger number, transaction, andamounts, is well. known in the art, and. therefore, only a briefdescription will be given herein. The date, consecutive numberingdevices, and the electros are carried on printing cylinders of the typeso own and described in Letters Pat ent of the United States issued toH. Cook, on September 27. 1892, No. 483,511, and to lVilliam Murphy,issued on June 18, 1895, No. 541,247, and reference may be had there tofor a detailed description. To such cylinders are provided, one forprinting on the front and the other for printing on the back of thecheck. The consecutive number type wheels are mounted on a shaft (Figs.7 and 8) carried by a cylinder 136 and which projects beyond the rearend thereof. Se cured to the rear end of the shaft 135 is an arm 137provided with a roller 138 which projects into an eccentric slot 139 ofa disk 14. pivotally supported on a stud 141 carried by the side frameof the machine. Astud 142 carried by the disk 1 10 projects into thebifurcated por ion of a lever 143 (Fig. 7), for the upper cylinder andaids in the support of the disk 14:0. The lower disk 14.0 sup ported bya stud 141 and by a stud 331 (Fig.

9) which projects into a slot 330 in a link 320. Once during eachoperation of the machine cach cylinder 136 is given a complete rotationby means hereinafter described, thereby rotating the arms 137 therewith.As each arm 137 rotates, the eccentric cam slot 139 will cause the arm137 to be oscillated once during each operation of the machine. Alsosecured to the shaft 135 is a frame 144 upon which is pivotally mounteda tined actuating and carrying pawl 145 adapted to add one into theconsecutive counter 146 every time the shaft 135 is oscillated. Aliners147 are provided for maintaining the consecutive number wheels in theproper alinement after they have been adjusted.

The date wheels are adjusted manually by knobs 150 (Fig. 10) in theusual and wellknown manner.

A perforator blade 151 (Fig. 8), is secured to the upper printingcylinder for perforating the check paper as it is being fed by thecylinder. The location of the perforation on the issued check is shownby dotted lines in Figs. 13 and 14..

Both the upper and lower cylinders are removable from. the machine forconvenience in changing the electros. A removable hearing 152 (Fig. 10),is provided. for each cylinder. These bearings are held in position byscrews. A shaft 179 projects from the rear of the upper cylinder into apinion 175, (Fig. 22), to be presently described, and which has abearing in the printer frame 177. In order to remove the upper cylinderit is only necessary to remove bearing 152 after which the cylinder canbe withdrawn from the pinion 175. The lower cylinder has a shaft 153(Fig. 11) projecting into the printer frame 61 and can be withdrawntherefrom after its removable front bearing 152 is detached.

Ghee/c paper feed The check paper is fed from a supply roll 155 (Fig.10), through a paper chute 156 (see also Fig. 11), between the lowerprinting cylinder 136 and an impression roller 157, through a paperchute 158 between the upper printing cylinder 136 and an impressionroller 159, through an opening in a stationary knife blade 160, betweenthe slip table 161 and a ribbon guard 162, from where it is ejected,after it is severec, into a retainer 163 (Fig. 10). Each printingcylinder 136 is provided with a feeding flange 164 (Fig. 8), which is ofsufficient length to feed the check paper far enough to issue one checkat each operation of the machine. The impression rollers 157 and 159cooperate with these flanges 164 for feeding the paper. Ink rollers 165(Fig. 11), are provided for each printing cylinder for inking the typeand electros thereon, so that the proper impression may be made.

The means for rotating the cylinders for causing the check paper to befed is also old fore ,chut e away from the cylinder after the machin estarts to. operate.

170 which projects into an opening 171 (Fig.

22), of a pair of knife-operating cams 172. The cams 172 are mounted onastud 173 and have securedthere'to a pinion 17 4. The pinion 17 4 mesheswith the before mentioned pinion 17 5 having a hub 176 which isjournalled in the printer frame'17 7. The cams 172 and the frame 61'hold the pinion 175 against lateral movement. The hub 176 of the pinion17 5 is provided with a slot into which projects the flattened end ofthe shaft 17 9,. before mentioned,.projecting from the rear of the upperprinting cylinder 136. Secured to the 'forward end of the printingcylinder is a gear 180 (Fig. 11), meshing with a gear 181, secured tothe upper impression roller 159, to the other end of which is secured agear 182. The gear 182 meshes with a pinion 183 meshing with a gear 185secured tothe rear ofthe lower printing cylinder 136..

Knife mechanism A knife mechanism is provided for severing the'checkpaper during each operation in which a check is issued. This mechanismis operatedby 17 2 (Fig-.22) which are adapted to rock a lever 200,pivoted on a stud 199 carried by the frame 17 7', once during eachoperation of the machine. Pivoted to the lever 200 is a link 201provided with an L-shaped slot 202 i at the lower end thereof. A stud203 carried by an arm 204 projects into the slot ofthcslot 202 asshownin Fig. 22; The arm description it is apparent 76 receives itscomplete 'rota-.

The blade210 is adaptedto slide between two spring-pressed blocks 212 (Figs. 11and 25). The blocks 212 are provided with oppositely facing flanges,overlying the blade 210, and which hold the blade 210 firmly against thebefore mentioned stationary blade 160, secured to a cross-bar 213carried by the frames 177 and 206. The blocks 212 are secured to thecross-bar 213, by screws which pass through countersunk holes in, theblock 212.

and bears against the. head thereof and against the shoulder in thecountersunk hole.

The check' aper passes through an o ening and therefore, when the cams172 causethe blade 210 to be-raised by means of the arm 200, link 201,arm 204, shaft 205, and arm 207, the paper iscarried against the cuttingsevered. q

Lower impression mechanism The lower impression hammer220 (Figs. 11, 19and 21) is adapted to make two impressions at eachoperation of themachine, during which a check is issued. This hammer is adapted to bewhen a slip is to be printed, for one of those impressions from ta Thiscontrol will be described when consid ering the slip printing mechanism.

The hammer 220 is normally in its dispreventing z charged position,shown in Figs. 11,18 and 19,

and is retracted by an arm 221, which carries .a stud 222 projectinginto aslot in a bell crank223 (Figs. ll'and 19),loosely-mounted on astud22 l carried by the printer frame 61. The bell crank 223 is providedwith a stud 225 (see also Fig. 16) whichis adapted to engagean arm of alever 226 (Fig. 19), also pivoted on the stud 224. A rearwardlyextending arm of the lever 226 is connected to a tripping arm 227, alsoloosely mounted on the stud 224, by meansofa stud 228 and a hub on thestud 224. A powerful spring '229 norm ally holds the arm 227 against ablock 230 carried by the frame 61.

As previously stated the shaft 75 is oscillated once during eachoperation by the arms 77 and 79, link 78 and sh'aft 76 (Fig. 3).

These parts' are so located, at normal, that the rotation of the shaft76, rocks the shaft 7 5 first clockwise, then counter-clockwise past itsnormal position,- and finally clockwise to tuating the hammer 220 totake the first-iming place- A spring surrounds each screw 1 the blade210 and the stud pression during a check will now be described.

During the first clockwise movement of the shaft 75 and consequently ofthe arm 221, will cause the bell crank 223 to printing operation rock ina counter-clockwise direction, there by rocking the lever and thetripping arm in a counterclockwise direction aga' the tension of thespring 229, until the tripping arm 227 latched in its retracted positionby a pawl 2235. The pawl 235 tends to rotate in a clockwise direction ona stud carried by the frame 61, under influence of a spring attached toa link (see also Fig. 15) pivoted to the pawl One arm of the hammer 220is provided with a stud .239 (Figs. 19 and 21) held in engagement withthe arm 226 by a light spring 240 stretched between a stud on the hammer220 and a stud on the arm 226. llherefor the hammer 220 follows the arm226, and since the latter and the tripping arm 22h arelatched by thepawl 25-35, the hammer- 220 is likewise retained in its retractedPOS'itlUIl ready to be tripped and discharged to tak an impression fromthe type wheels.

To release the han'imer 220 the pawl must be raised and disengaged fromthe arm For thispurpose the arm 221 carries a stud 241 which is normallyquite some distance below the link 238. As the arm is receiving itsfirst clockwise movement the stud 241 is moved idly still farther fromthe link 238.

- 241 contacts the link 2238 and raises the same sufficiently todisengage the latch 235 from the arm 227.

By the time the stud 241 reaches the lower end of the link 238 to raisethe same, the stud. 225 will have been moved upwardly past its normalposition so as to give ample clearance between the same and the upperedge of the arm of the lever 226 when the latter is re leasedas the pawl235 is disengaged from the arm 227.

When such (lise-ngagement takes place, in the manner above stated, thespring 229 rotates the lever 226 and arm 227 rapidly in a clockwisedirection until stopped by the block 230. This rapid movement of thelever 226 and arm 22? will cause the hammer 220 to be rocked rapidly ina clockwise direction. \Vhen the arm 22'? is stopped by the block 230the momentum of the hammer will be sufficient to overcome the tension ofa light spring 240, and the hammer moves upwardly to take an impressionfrom the type wheels, after which the spring 240 will lower the hammeruntil the stud 239 rests on the lever 226.

After the first impression has been made as just described, the knifemechanism is operated to sever the check after which the check-ejectormechanism is controlled, in a manner to be hereinafter described, tofeed the severed check into position to receive a second impression. Asjust above stated the arm 221 is moved first, in a clockwise directionto retract the hammer for the first impression, then in acomiter-clockwise direction pastnormal position to release the hammer,and then clockwise to its home position to operate the hammer to makethe second impression. The mechanism for making the second impressionisbest shown in Fig. 18. Piroted en the hammer 220 a link 245 providedwith a stud 246 which projects into a slot in an arm 247 pivoted on astud 248. The link is held in position by a spring 344 wound around theid 2335 and lining one end against a stud on the hammer and the otherend against a stud on the link 245. The slot in the arm 247 limits themovement of the link toward the left. The link 245 is provided with ashoulder 249 with which a block 250 secured to the arm 221 is adapted tocooperate on the second clockwise movement of the arm 221 as the latterreturns to normal. The link 245 is pivoted on the abovementioned stud239 which is held in engagement with the arm 226 by the light spring240. From this it is apparent that when the block 250 engages theshoulder 249 during its downward movement, it will cause the hammer 220,together with the arm 226, to be rocked counterclockwise therebystretching the spring 229 in the same manner as that accomplished by thebell crank 223 above described. The lower portion of the slot with whichthe stud 246 cooperates is so shaped that when the link 245 is moveddownwardly by the arm 221, it will cause the shoulder 249 to bedisengaged from the block 250, thereby peri'nitting the spring 229 torock the arm 226, together with the hammer 220, rapidly in a clockwisedirection, until the arm 227 is stopped by the block 280 therebyarresting the lever 226, whereupon the hammer 220 will continue to moveunder influence of its momentum to take an impression in the mannerabove described.

During the time that the arm 221 is retracting the hammer 220,preparatory to talk ing the second impression, a means must be .rovidedfor rendering the pawl 235 (Fig.

1.1)) i ifccti ve, thus preventing the pawl from latchmg the arm 227 inits retracted posiiion. This means is a part of the check feed andejector mechanism shown in Fig. 24 and to bepresently described, but itWlll be necescarried by the pawl 235, thereby raising the .pawl 235 upand preventing from latching the arm 227 in its retracte position sothat off the block 250et-he when the link 2&5 slips the hammer 220 asspring 229 can operate previously described.

Check feed and ejector mechanism The check feed andejector mechanism isadapted to feed the check between the two printing operations, as abovementioned, and after the second impression has been taken, to eject thecheck from the machine and into the receptacle 163 (Figs. 1 and 10)."The method of feeding the check between impressions will be describedfirst.

The before mentioned rocking arm "221 (Figs. 11, 22, 23 and '24), isadapted to first retract the segment 255, in which position it islatched until after the first impression is made, then the lower end ofthe arm 221 will unlatch the segment 255 and control the amount ofmovement thereof for feeding the check into position to receive thesecond impression.

' the same from the arm The means latching the same, the check prior tonow be described.

Mounted on the arm 221 is a (Figs. 22 and 23) which as the arm221receives its initial clockwise movement, engages an arm 257 on thenreleasing it to feed the second impression, will between a stud 261 onthe frame 6l and a '7 stud on the latch 258 normally holds the latch 258in engagement with the stud 261'. The latch 258 is provided with aflexible pawl 263 which lies in the path of the end 26 of the arm 221.When the arm 221 is rockedcounter-clockwise after segment 255 has beenlatched in its retracted position, the of the arm 221 can pass theflexible pawl 263, but upon the return or second clockwise movement ofthe arm 221, as the latter returns from its past normal to its normalpositiomthe end 264 thereof will engage the pawl 263 and rock the latch258, thus disengaging Upon such disengagement of the arm 257 from thelatch 258, the spring 262 rotates the feed and ejector segment 255clockwise from the position shown in roller 256.

7 the segment 255 and rocks thelatter counter-clockwise against the v alatch end 264 4 257 of the segment V Fig. 27 to that shown in Fig. 24,whereupon the arm 257 contacts and is stopped by a block 265 on the arm221. The above release and clockwise movement of the feed and ejectorsegment 255 take place? just prior to the engagement of the block 250with hammer retracting link245, and as the segment 255 meshes with apinion 266 (Figs. 21, 23 and 24) connected bya sleeve 268 to a feedroller 267, the latter a tension roller 269, to be later described,feeds the check in position to receive the second impression.

After the second made, and as the arm 221 completes its second clockwisemovement to normal, the block 265 passes off the arm 257, therebypermitting the segment 255 to be rotated rapidly under action of thespring 262 until the projection 251 engages the block 230 61, therebycausingthe check to be ejected from the machine and into the receptacle163 as above mentioned.

perforation across the check is made and all ofthe printing, as shown inFig. 13, with the previously called the second impression, and

the third line is'what has been called the fir-S5165 impression. Thecheck is fed into position to receive the first impression by theelectro and impression rollers above-mentioned. It is then severed, thefirst impressionis made;

it is then fed and the second impression is made, after which it isejected.

During the first clockwise movement of the shaft 75 and arm 221 thehammer 220 is retracted by the lever 223 and the roller 256 on the arm221 retracts the feed and ejector segment 255 which is held in retractedposition by the latch 258. The hammer is held in its retracted positionby the pawl 235.

' During the counter-'cloclnvise movement of the arm 221, after said armhas passed its normal position and near the end of the move-1 mentthereof the pm 241, through the link 238 raises the pawl 235 andreleases the hammer to the action of the spring 229, whereupon the firstimpression is made.

Duringthe second clockwise movementof the arm 221 as it returns to 'its'normal position. the end 26-i-thereof releases the latch 258 from thearm 257 of the check feed and ejector segment 255,

moved clockwise and feeds the check into" whereupon the latter isposition to receive the second impression. The feed stops when thetllIIl 257 strikes the block 265 on the arm 221. The block then contactsand draws the link 245 downwardly thus retracting the hammer a. secondtime, and upon continued movement of the arm 221 the link is releasedfrom the block 250, thus freeing the hammer 220 to the action of itsspring 229, which effects the second impression.

After the second impression, and as the arm 221 makes its secondclockwise movement to normal, the block 265 passes off the arm 257,whereupon the spring 262 rotates the check feed and ejector segment 255to eject the check into the receptacle 163. This ejecting movement takesplace substantially at the very end of the operation of the machine.

The receptacle 163 is carried by the cabinet of the machine, and isprovided with a pivoted check retaining detent 271 (Figs. 1 and 10).This member lies on the bottom of the receptacle and is forked as shownin Fig. 1. As the check is ejected it is forced under the detent 271thereby preventing the check from being ejected entirely from themachine. The opening between the forks provides a finger hole forconvenience in re moving the check from the receptacle.

The tension roller 269 is controlled by the knife cams 172. (Fig. 22)and is so timed that the check paper will be gripped between the rollers267 and 269 before the knife has completely severed the paper. Securedto the shaft 205 is an arm 280 provided with a stud 281 which projectsinto a slot in a link 282 nrried by a stud 283 mounted in an arm 28 onwhich the tension roller 269 is mounted. The stud 283 projects into aslot in the link 282 and a spring 285 stretched between the stud 283 anda stud on the link 282 holds the lefthand end of the slot against thestud 283. A spring 286 stretched between a stud on the arm 284 and thelink 282 normally tends to hold the tension roller 269 separated fromthe feed roller 267. However, when the shaft 205 is rocked in acounter-cloclnvise direction by the cams 172 as above described, thelink 282 is moved to the left (Fig. 22) and through the spring 285 andstud 283, rocks the arm 284% in a clockwise direction, thereby carryingthe tension roller 269 into engagement with the check to press itagainst the feed roller 267. The movement of the link 282 toward theleft, is greater than necessary to carry the roller 269 against thecheck therefore, the left-hand end of the slot is moved away from thestud 283 thereby permitting the spring 285 to hold the roller 269 inengagement with the check to firmly press the same against the roller267.

Since the release of the check ejector mechanism is so timed that thecheck will not be ejected until after the machine returns to its homeposition, therefore,

it is necessary to provide some means for holding e tension roller 2.69in its check pping pos ion until after the shaft 2\ 5 r tion.. Thesegment 205 1' uses this after the check has been ejected.

Mounted on the rightliand t rd of the link 282 (Figs. 21, 22. and 2.6)is a ssud 299 which projects into a' bifurcated arm 291 carried by thestud 22 1a. The arm 291 is connected to an arm 292 by a yoke The arm 292is provided with a finger 294; bent at right angles thereto and whichprojects into the path of a step 295 on a vertically disposed slide 296.The slide 296 is mounted on two studs 297 and normally tends to moveupwardly under influence of a spring 298. An car 299 near the upper endof the slide 296 normally engages the' shoulder 251 of the segment L55,thereby preventing the slide from moving upwardly. However, at thebeginning of an operation of the machine, the segment 255 will be movedaway from the ear 299, thm'eby permitting the step 295 to move upwardlyto contact the I When the shaft 205 is rocked as above mentioned and thelink 282 moves toward the left (Fig. 22), the stud 290 will rock the arm291 and the finger 29% clockwise to move the lower edge thereof out ofthe path of the 295, and in so doing the slide 296 is cannned downwardlyvery slightly, and when the lower edge of the finger 29% passes oil ofthe step 295, the slide 296 springs upwardly to position the left-handedge of ti step 295 into the path of the right face oi one linger 294.W'ith the end of the step 295 in. the path of the right face of the lingr 2 .1 arm 28ft is prevented from rocking counlrn clockwise to separatethe tension roller 269 from the feed roller 267. This construction isnecessary because the link 282 mus rocked back to normal pOf' ti\ .)llduring latter part of the operation of the machine, whereas the segment255 is released for ejecting the check at the very end of this opera.tion. Therefore it is necessary to maintain the tension roller in itscheck-gripping position after the machine returns to its home pothesition and until after the check ejected.

step i from operating the consecutive number mechahole 311 in the framenism, the knife, the check ejector, and the check impression hammer, sothat no check will be issued and nothing will be added to theconsecutive number device. This knob 305 is securedto a shaft 306 (seealso Fig. 6) to which is also secured a segmental plate 307. Alsosecured t'o shaft 306 is a collar 308 (Fig. 11) to which one end of acoil spring 309 is attached. This spring is wound around the shaft306and the other endbears against the frame 1'77. T he spring 309constantly tends to rotate the shaft 306 to its on position. Thismovement, of the shaft 306 is limited by the engagement of the segmentalplate 307 with a stud 304 carried by the frame 177. The segmental plate307 is provided with astud 310 (Fig. 6) ,adapted to enter a 177 when theknob is in If, rhoweverpit is demechanisms, the knob is'forcedbackwardly until the stud 310 is disengaged from the hole 311 and thenthe knob isturned counter-clockwise against the tension of the spring309 until the stud 310 registers with an opening 3127in the frame 17 7(Fig. 11) whereupon the spring 309 will force the shaft 306 outwardly toenter the stud in the opening 312, thereby holding the knob in its offposition. When it is desired to throw the mechanism back on, all theoperator needs to do is press in on the knob 305, thereby compressingthe spring 309 until the stud 310 is again disengaged from the. opening312 whereupon the spring 309 will rotate the shaft 306 in a clockwisedirection until the segmental plate 307 engages the stud 304 in whichposition the stud 310 is in proper alinement to enter the opening 311,in which position the knob is in its on position.

Vhen the knob is turned in a counter-clockwise direction from its on toits off position as above described,'a stud 313 on the segmental plate307 will engage a downwardly extending lug 314 of a link 315 connectinga lever 316 and a bell crank 317. A spring 318 normally tendsto move thelink 315 toward the right. When the pin 313 en the lug 314 it will movethe link 315 toward the left and rotatethe bell crank 317 in acounter-clockwise direction, thereby rotat-ing an eccentric shaft 319upon which it is secured. Mounted on the eccentric portion of the shaft319 is the before mentioned imthe on position. sired to disable these.pression roller 157. Rotation of the shaft 319 will cause theimpression roller 157 to be moved away fromthe printing cylinder feedingflanges 164 (Fig. 8). Pivoted to the other arm of the bell crank 317 isa link 320 which is also pivoted to an arm321 secured to an eccentricshaft 322 for the upper impression roller 159. Rocking of the bell crank317 counter-clockwise will lower the link 320 thereby causing the shaft322 to be rotated in a counter-clockwise direction, thus moving theimpression platen 159 away. from the feeding flanges of the upperprinting cylinder. From this it is evident that when the knob is in theoff position, the check paper will not be fed, because both theimpression rollers 157 and 159 willhave been disengaged from theirrespective printing cylinders.

Cut in the link 320 is a slot 330 into which a stud 331, carried by thecam disk 140 (Fig. 9), for the lower cylinder projects. When the link320 is lowered as just described, the slot 330 will permit the cam disk140 to rock in a counter-clockwise direction about the pin 141 as apivot. This movement of the cam disk 140 will move the cam race 139 to aposition in which it is concentric with the shaft 153 which forms therear bearing for the lower cylinder 136. When the cylinder is rotated,in a manner heretofore described, with the cam disk in this position, itwill have no effect upon the arm 137, and therefore, nothing will beadded into the consecutive num-- ber device for the lower printingcylinder.

Mounted on the arm 321 (Fig. 6) is a stud 334 which projects into abifurcation in the before mentioned lever 143, which is mounted on thehub 176 of the gear 175 (Fig. 22). Whenthelink 320 is lowered as abovedescribed, the arm 321, by means of the stud 334, will cause the lever143 to rock in a clockwise direction, thereby rotating the cam disk 140(Fig. 7) in a clockwise direction, about the stud 141. as a pivot,thereby moving the cam race 139 for this cam disk into a position inwhich itis concentric with the shaft 179. Then, when the upper cylinder136 is rotated as above described, the cam race 139 for the uppercylinder will have no effect upon the arm 137, and therefore, nothingwill be added into the consecutive number device for this cylinder.

\Vhen the knob 305 is moved to its off position, the severing mechanismis also disabled. Pivoted on the stud on the before mentioned arm 321 isa link 340 provided with a slot surrounding a stud 341 carried by thelink 201. When the link 320 is lowered as the knob ismoved to its offposition, thereby causing thearm 321 torotate in a counter-clockwisedirection, the link 340 will move the link 201 to the left (Fig. 22)thereby causing the elongated portion of the slot 202 to of the stud203. Now. rocked by the cams the link201 will move idly up and downwithout moving the shaft 205, thereby disabling the operation of theknife blade 209.

The disabling of the knife mechanism, as just described, will alsoprevent operation of the mechanism for moving the tension roller 269,into its check-gripping position. It will be remembered that the arm280,which is also when the shaft 205 is be moved into the path 3 334(Fig. 22), a

secured to the shaft 205, performs this func; tion, and since thedisabling of the'knife prevents movement of the shaft 205, it isapparent that the tension roller 269 will remain in its loweredposition.

The n echanisn'i for releasing the printing hammer after it has beenretracted by the bell crank 223, will be ineif ctivc with the knob inthe i if position, because the link 238 will be moved to the right farenough so that when. the stud 211 on the arm 221 (Fig. 19) travelsupwardly it will not engage the lower end of tile link. On allsubsequent operations of the in line, with the knob in the off position,the hannner will remain in its retracted position. \Vhen the knob ismoved back to the on position and the machine is operatml, ti on, at theproper time during the operation of the machine, the hammer will againbe released to take the proper impression.

The before mentioned lever 316 is provided with a rounded top -ll2 15)against which the link 238 is normally held by the spring 237. 315 movedto lVhen the link the left (Fig. 15), as above described, the roundedtop of the lever 316 will l e moved to the right, thereby permitting thespring 237 to rock the link 238 to the right. When in this position thebottom of the link 238 will be out of the pat-h of the stud 241 on thearm 221, and therefore, when the machine is operated the stud 2 H willnot engage the link 238 to release the retracted impression hammer, andtherefore. no impression will be taken.

It is also necessary to move the link 245 (Fig. 18), to its incll'ectiveposition so that the block 250 will not engage the shoulder 2-19thereof. Securcr to the lever 316 by means of a stud 34-3 and the hub ofthe lever 316 is the before mentioned arm 2-Llfll It will be rememberedthat the stu d 2&6 on the link 245 projects into a slot of the arm 24?.From this it can be seen that when the link rocks the lever 316clockwise, the arm 24.7, by means of its slot and the pin 246, will rockthe link toward the right Fi '18), thereby moving the shoulder 2-H)out'of the path of the block 250. From this-it is apparent that thesecond impression of the hammer will also be prevented.

As previously stated, the spring 3 A (Fig. 18) is wound around the studOne end of the spring eng a stud on the hammer 220, and the other a studon the link 2%, thereby holding the stud 246 against the lefthand edgeof the slot in the arm 2&7.

During an operation in which a check is not to be issued, thecheck-ejector releasing mechanism is rendered inell ective so that thesegment 255 (Fig. will remain in its retracted position until a check isto be issue The lever 3l6 is provided with a nose in the path of whichlies a stud 345 on the flexible pawl 263. \Vhen the lever 316 is shiftedto the right by the link 315 the upper edge of the nose thereon willengage the stud It is desired to print a sales slip every time themachine is operated with either a re ceived-on-acc0unt, charge, orpaid-out" key, depressed. no matter in what position the on or oil' knobmight be. {When the knob is in the on position, the transactirm keyswill throw oil the second in'ipression. When the knob is in the offposition, the special keys will control the mechanism whereby the firstimpression is automatically thrown back on. It is always desirable tothrow off the consecutive numbering. check feeding and severingmechanisms when a special key is depressed. The mechanism foraccomplishing this is substantially the same as that described under thecontrol of the on and oil knob, and therefore only so much of it as isnecessary to explain how it is cont-rolled by the special keys will begiven here.

The cabinet of the machine is provided with an opening through which theslip table 161 (Fig. 10) projects. The check receptacle 163 is providedwith a pivoted slip detent 350 which has an upwardly turned lip 351 andwhich lies on the slip table by. its own weight. The slip is placed onthis table beneath the pivoted detent 350 in the proper position beforethe machine is operated.

Adjacent to the bank of keys (Fig. (i), which contains thereceived-ou-account, charge, and paid-out keys, is a segmental plate 352which lies in the path of the studs 66 on the transaction keys. Theplate 352 is slidably mounted on a link on studs 354.. Mounted on theplate 352 is a block 355 which lies in the plane of ahell crank lever356 pivoted on a stuc 357 carried by the machine frame 31. The bellcrank lever 356 provided with a roller which cooperates with the beforementioned cam 100 which is adapted to rock the bell crank lever 356clockwise during each operation of the machine. A spring 34.9 holds theroller on the bell crank lever 356 in engagenn-mt with the earn 100 atall times. Depression of any of the keys (55 will cause the stud 66 toengage the plate 352 and slide it inwardly on the link 353 to positionthe block 355 behind the cam surface 358 of the bell crank lever 356.hen the cam 100 rocks the bell crank lever 356 clockwise, the camsurface 358 will engage the block 355, and move the plate still furtherimvardly. The initial movement of the plate 352 will move tl studs 35+to the left hand ends of the slots in the link 353. Now when the bellcrank lever 356
